Hello everyone, this problem has several steps and I'm studying for an exam, so i need to get all of them! The first part is:
Let C be the curve with equations x = 2-t^3; y = 2t-1; z = ln(t);
Find the point where C intersects xz-plane. So i said let y = 0; and i'd get
Po = (z-t^3,0,ln(t)), but i don't t hink this si right because isn't x, y, and z unit vectors? like <2-t^3,2t-1,ln(t)>?
So once i find this, I'm suppose to find the parametric equations of the tagnent line at (1,1,0); then find an equation fo the normaml plane to C at (1,1,0); I think if i can get the first part i can figure out the rest! thanks!
